DARKSOFT The Definitive Guide to Fixing Your CPS2 Multi Kit

Did you check the jumpers on the B board? What PAL are you using? Some pins might look OK but a continuity test will clarify any issues.

Yes Verified the jumpers on both the V6 Asia and V7 USA setup and both were correct as for the original set of instructions, I also re-flashed the firmware just in case but despite all that the behavior was the same on both occasions. I also reverted both board sets to stock form with a infinikey and verified them both running their original games without any graphical issues. Thanks for the quick reply, both B boards had Pal Gs.

Did you run the verify romset?

I ran it but unfortunately the contrast pot went bad on me and I could no longer see the LCD. I did order both replacements for the contrast pot and 20 pieces of the buffer chips. I had another one I did for a friend that was fixed by swapping buffers. This one looks way worse so I think it's deeper than that this time.

Make sure none of the tiny black 3 and 4 pin components have been knocked off.

Where is that located? Got a picture?

They are all over the pcb. Tiny black boxes. They tend to get damaged if something accidentally hits the pcbs.

Could firmware also cause this issue?

Maybe it got somehow corrupted. You can try to update.

as this was an older kit I did upgrade the firmware and did not soldered the key writing wire until after, maybe I used the wrong file? I know there is one specific to the old kits right?

Hi, had the cps2multi from saveyourgames.it since day 1 and working fine, last play was around 3weeks ago.
Fired it up tonight and got greeted with an "eeprom error" message from SSF2T New Legacy.
Reseated all the boards with no bent pins or any abnormalies from visual inspection of the boards.
Tried to flash 1944 (black screen on boot) AVP (a wall of error addresses) and lastly Choko (Ceeprom error, attached pic for reference)
How could I rectify this issue?

Any help appreciated
